BlackBerry is back, better than ever and looking to do battle with the biggest company in the tech world, Apple. BlackBerry CEO Thorsten Heins slammed Apple in a conversation with USA TODAY's Jon Swartz earlier this week, calling the iPhone "passé" and saying Apple "has lost its innovative edge."

However, he admitted that BlackBerry has fallen on some hard times lately. "We have the same issues as Apple. We need to earn our laurels back. We have a long way to go."

But Heins is optimistic that BlackBerry can make a comeback. He said he "can't wait" to launch the Z10 and he is willing to "fight for customers."

With the Samsung Galaxy S4 unveiled, USA TODAY's Mike Snider took it for a spin at last week's South By Southwest festival.

We've told you all about the S4's many features, but how is it in action? Snider had only good things to say about the phone. He was impressed by S4's hover touch feature (you don't even have to touch the screen to open e-mails!), its many camera modes and its smart remote-control feature.

A Samsung communications specialist told Snider the company is "pretty proud" of the S4 and we can expect to see it in stores later this year.

Is NASA's Voyager I spacecraft the first man-made object to leave the solar system? NASA isn't sure.

The spacecraft has wandered past the edge of the "heliosphere," the boundary between the edge of the solar system and interstellar space, at least a few times since its launch in 1977. The size of the heliosphere expands and contracts based on solar winds.

Astronomers reported in August that the Voyager was reporting cosmic ray intensities only found outside our solar system. But NASA recently said they are skeptical of these findings. They believe Voyager is in a newly discovered boundary region "at the edge of our heliosphere." Both sides are expected to release more papers in the coming weeks dealing with the dispute.

If you have a love/hate relationship with TiVo, you may want to reconsider your stance with the arrival of Mini TiVo. The small plastic set-top box can extend the saved shows on your main TiVo box to a second TV in your house.

The mini box doesn't have all of the features of the full-sized TiVo box. But you can use it to watch prerecorded shows, get Season Passes, watch TiVo's movie "collections" and more.

Ed Baig did a test run of the Mini TiVo and said that while it was cheaper than buying a second full-size TiVo, it has a few flaws. The Mini doesn't work over Wi-Fi, doesn't have Netflix and tacks on its own separate service fee of $5.99 a month or $149.99 for the life of the Mini.

However, Baig says that "despite their limitations, the Mini and TiVo Stream work well enough to have you consider rekindling your relationship with TiVo. Or sparking a brand new romance."

Product development at car companies is going high-tech with new 3-D printers. The new device can turn a pile of aluminum powder into a working car prototype in less than a week, sometimes even just one or two days. This is a vast improvement over older car-development methods that relied on outside machine shops and took as long as three or four months.

The 3-D printers could also revolutionize the way other products are developed. Experts told USA TODAY's John Shinal that some developers are starting to use 3-D printers for bicycle helmets, prosthetics and ear buds.
